- COMBINATION HEADREST AND SERVER.

Application filed June 5,

To all whom it may concern:

Be it known that I, GEORGE W. .SPAHR; a citizen of the United States, residing at Mechanicsburg in the county of Cumberland and State of Pennsylvania, have invented certain new and useful Improvements in Combination Headrests and Servers; andI do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and usethe same.

This invention relates to an improved head rest and server for use on barbers chairs and has for its object to provide a mechanism which will automatically servev or feed a clean portion of paper over the head rest after the latter has been used by a customer. The improved device embodies means for automatically holding certain movable parts of the mechanism in a given position to prevent accidental operation of the serving mechanism until such time as it is desired that the serving mechanism shall function.

The above and other novel features of the invention will appear from the detailed description taken in connection with the two sheets of drawings forming part of this specification.

Referring to the drawings, v

Figure l is a side elevation of the improved head rest and server showing the a same as attached to theback of a barbers chair;

Fig. 2'is a rear elevation of the same; Fig. 3 is a section taken on line 33 of Fig. 2;

Fig. 4 is a Fig. 2; r

Fig. 5 is a section through the mechanism for operating and controlling the rotation of the roll which serves to unwind the paper from its spool, and '7 Fig. 6 is a View showing the position of the automatic locking means when the head rest is in substantially upright orout-of-use position. 7

In the drawings, 10 designates the adjustable bar which projects upwardly from the back of the barbers chair and to which the head rest is adapted to be removably secured by means of a socket 11 which projects downwardly from a cross piece 12 section taken on line 4l i of 1922.- Serial No. 565,903.

which, at its terminal ends is pivotally secured as at 13. to the side walls lt of the l.

head rest. the head rest is turnably'mounted withre- .spect to the socket 11, the pivotal mounting .13 being-- at the lower'rear corner of the the back ofthe head rest. Thisplate is senor as by screws 15'.

Mounted on plate 15 is a U-shaped catch 16 and mounted on one wall 14 is a weight? ed hook or latch 17 which is adapted to incured t0 the cross piece in any suitable man terlock with the hook 16 in certain positions of the head rest,'(see .F ig. t). Mem-' bers'l6 and 17 may be termed an automatic locking device and the purpose of the same will presentlyv appear.

It will now be understood that Mounted on the other wall 14 is a case 18 within which is contained'mechanism for controlling rotational'movement of a rubber roller 19 between; which and a rubber roller 20, the serving'paper 21 is adapted to pass, the paper being mounted on a spool 22 at the other end of the headrest frame, it

being understood that the paper leads from the spool 22 over a padded cushion 23 on the front face of the head rest frame. Upon turning of the rubber roller, paper is drawn from the spool over the headpad 23. At this point it maybe stated that roller '20 19, there'being a spring 20 which tends to move the roller 20 into frictionalengagement with roller 19. To allow for relatlve displacement of roller 20, the axle ends 20 of the same are mounted in slots 20 in the walls 14 (see Fig. As shown, the spring 20" Ire-acts against one of the cross rods 14 which serve to maintain the walls '14: in spaced, rigid relation. s I

The mecha'nismfwi'thinjthe case 18 will now be' described. Referring to Fig.- 5, it will be seen that the'case is'pr'ovided with a guide-way 24 within which is mounted a slide or bar 25. The front of this bar is provided with rack teeth 26 and thefback thereojfwith ratchet teeth 27 I Disposed at right angles to the guideway 24 is a com- .isyieldingly mountedwithrespect toroller municating guide-way within which is mounted a slidable ratchet tooth 28 which is adapted to interlock with the ratchet teeth 27-. Mounted in a passage at the lower end of the case 18 is a cam lever 29. The upper end of this leiter is, suitably connected to the ratchet tooth 28 so as to move the latter out of contact withv theteeth 27 on the.

bar 25. Secured t0 the casing 18 is a leaf spring 30 which is adapted to bear against the springtooth 28 to force the same into engagemeiit with the teeth 27; on the bar 25f The end; of the slidable tooth 28 -in engagement with the spring is preferably beveled as at 28- in order to lower the contact 'point with the spring. The lower end of the cam lever 29' is'provided with a toe 31 which is adaptedto engage with a contact piece 32 mountedv on' the plate 15 (see F ig, 3).

Referring to Fig. 3, it wil'ljnow be seen that when the plate 15 is moved in the direction of the arrow afthe contact piecev 32 willco-act with the toe 31 to swing the cam lever in adirection away from the cross piece 12. This movement of the lever will; serve to disengage the ratchet tooth plate 28. from the teeth 27 on the bar 25 for a purpose thatwill presently appear. E'X tendinglaterally from the slide 25 is a shelfj33 which forms a seat for. an expansion spring 3 1 which at its other end reacts against a bracket 35 secured'f to the case 18. The spring. is compressed by inward movement of the plate 15 which carries a post 36 which isscrew-threaded' with the plate. Adjustment of this post determines the amount of paperthat is served by con- ,movementby the heel 1'7 thereof seating inv trolling the displacement of the rack bar 33.' Ihe energy stored up in the spring.

will serve to rotate the roll 19 when the plate 15 is moved to operate the trip or lever 29.

When the barbers chair is tilted the weight of the head of the occupant serves toautomatically set the server as shown in EigsB ands l n' this position the latch 17? interlocks withthe jhook 16 toprevent accidental outward movement of the plate I 15.. r The center of gravity ofthe hook 17,

in said position, is such as to maintain the parts 16 and" 17 in interlocked relation. When the chair is, broughtto normal position, the latchl'? becomes disengaged from thehook 1-6, whereupon. the trip 29is rocked on its pivot 29' by movement of the plate 15' in; direetion of arrow-a to release the spring 54;v to, rotate the roll 19 for the purpose specified; Thereafter the plate 15 is locked by the gravity latch 17"'against inward the, seat 16 in -thehook IIlQIIlbBIg16.

'E e i e b w t plate l e is a ha 37 on which isfixed apinion 38, said pinion being in engagement with the rack 26 on briefly described. the improved head rest will be substantially the bar 25. At the other end of the shaft is fixed a ratchet wheel 39 and loose on the shaft adjacent the wheel 39 is a gear 40 which carries a pawl e1 adapted to engage with the teeth on the ratchet wheel 39. The gear wheel 10 is in mesh with a pinion 42 fixed on the shaft on which the roller 19 is mounted. It will: now be understood that when the slide or bar 25 is moved upwardly against the tension of the spring 84: by the plate 15 that the shaft 37 carrying the ratchet wheel will be rotated in a-counterclockwise direction as viewed in Fig. 1.

When 'the spring 34 functions to move the slide 25 downward the shaft 37 will be positively coupled to the gear 40 whereupon rotation will be imparted to the roller 19'.

Inasmuch as the paper is frictionally held against the roller 19 by the springpressed roller 20, a certain length ofhpa'per will) be unroll'ed from thespool' 22 when rotatlon is imparted to the roller 19. I

At one corner of the head rest frame. 18

mounted a shield which, at its lower edge,

is serrated to facilitate the severance of the paper which has'passed between the rollers 19 and 20. The head rest pad 23 is mounted on a hinged cover plate 44, the plate being hinged at the upper end of'the' frame as at 45 to. permit the cover plate to be lifted so to expose the roll of paper at the lower The lower end of the any suitable manner at the lowerend of the head rest frame. In the present instance,

there is provided a'cylinder 46 which has a slot 17 through which the paper 21 is passed,

the upper part oftlie cylinder being cut away to permit replacing of the roll within I the cylinder. 'The cylinder is securedjto the wails'l f of" he frame in any suitable manner.

In order to permit the inanua l drawing is provided. with aknurledthumbwheel '19 at one of itsends (see Fig.

The operation of the device willnow be The normal position of as shown inFi' 1, that is to say, slightly inclined to the vertical; The barber, pre

paratory to shaving a customer, tilts the chair backward until the liead' rest assumes the position shown in fiig's doraz The head of the occupant 1s now rest ng, on the pad23- and the weight of'the head is sufiicient to" rock the head frame about the axis 13 of the cross bar 12 whlch is secured to the of the paper across the pad 23, the roller 19 socket 11 which latter is teleseoped over the post 10 which. rises from the back of the barbers chair. As the head rest frame is rocked in the manner just stated the latch 17 engages with the hook 16, thereby preventing accidental upwardmovement of the head rest frame while the barbers chair is in an inclined position. Relative movement between the plate 15 and the walls 14 also serves to set the mechanism Within the case 18, the spring 34 being compressed. The compression movement of the spring is without effect on the roller 19. When the barbers chair is brought to normal position as in F 1, the latch 17 drops away from the hook 16 and the spring 34 thereupon causes the plate 1 to move outwardly relatively to the plate 14. This upward movement is accompanied by movement of the bar or slide 25 and hence rotational movement is imparted to the roller 19 through the train of gears in connection therewith as will be readily understood.

It will now be seen that a fresh piece of paper is brought in position over the pad 23 immediately after the barbers chair has been broughtto normal position and that the head rest is, therefore, always in sanitary condition as regards the serving paper. The portion of paper which has passed between the rollers 19 and 20 may be torn off and used as a lather paper for the following customer. V v
